Bitcoin (BTC) is the world’s first decentralized digital currency, launched in 2009 by an anonymous figure or group known as Satoshi Nakamoto. It operates on a peer-to-peer network without a central authority, relying on blockchain technology—a public, tamper-resistant ledger that records every transaction. Miners use computational power to solve complex mathematical problems, validating transactions and earning Bitcoin rewards, though this process is increasingly energy-intensive and competitive.
